Chapter 8.2 pp. 280-288 Electric Current

Electric Circuit ,[object Object],[object Object],[object Object],pp. 280 - 281

A Simple Circuit: A Battery, Conducting Wires, and a Buzzer p. 280 1) Chemical energy in battery gives electrons on the –ve terminal electric potential energy 2) Electrons are attracted to the +ve terminal and are pushed through the conducting wire to the buzzer 3) In the buzzer, the electrons’ potential energy is transformed into sound energy 4) Electrons travel back to the battery through the complete circuit

Circuit Components and Diagrams ,[object Object],p. 282 Source: the source of electrical energy Conductor: the wire through which electric current flows Load: a device that transforms electrical energy into other forms of energy Switch: a device that can turn the circuit on or off by closing or opening the circuit source conductor load switch
